SYSTEMATIC AEEANGEMENT OF THE SPECIES 
faucem attingentibus versus apicem crispato-finibriatis; stylis capillaceis ovarium obovatum seu globosum sequantibus; 
capsula tenuissima corollas rudimentis ad basin persistentibus indusiata apice libera stylis e basi lata subulatis paulo 
divergentibus coronata ; seminibus 2-4 lenticularibus rugoso-reticulatis. 
Chatham Island, of the Galapagos group; mostly on Leguminosce , common on a low annual Grotalaria, but also 
on trees, such as Parkinsonia and Mimosa% hanging down in massy festoons, Andersson! — Closely allied with both 
other Pacific species just described, distinguished from them by the very acute lobes of calyx and corolla and by the 
subulate styles; moreover from C. Sandwichiana by the presence of scales, and from C. gymnocarpa by the covered 
capsule and the direction of the styles; from C. acutiloba of the mountains of the neighboring coast and from C. urnbel- 
lata it differs by the inflorescence, by the baccate capsule, etc. — Flowers 1-1 j lines long ; scales adnate nearly to the 
apex, crenulate on the sides, fringed only at tip ; capsule about 1 line in diameter ; intrastylar aperture large, forming 
a transverse slit; seeds only 0.5 line long, dark brown in the specimen before me (perhaps not perfectly ripe) ; and 
strongly reticulate; hilum short, oblong-linear, perpendicular or oblique. — The specimens examined by me were all 
on a low Crotalaria. 
* * * Flowers arranged in branching paniculate cymes ; styles slender, as long or longer than ovary; withered 
corolla surrounding the capsule or covering its top. 
\/ 46. C. tenuiflora, Engelm.! in Gray, Man. ed. l, p. 350; ed. 2, p. 336. C. Cephalanthi , Engelm.! [498 (48)] 
in Sill. Joum. XLIII. 336, t. 6, f. 1-6.—Wet places, often on Cephalanthus , Salix, CormiSy and other 
shrubs, but also on Vernonia , Aster, and other herbaceous plants ; Missouri and Illinois, Engelmann! Geyer! Upper 
Missouri country, Hayden! New Mexico, Wright! 1629 (124); Arizona, the same! 1626 (578). — In young plants just 
beginning to flower the cymose-paniculate inflorescence is very distinct, — the terminal flowers of the main branches 
of the inflorescence opening first, and lateral clusters of smaller and ever smaller buds appearing lower down on the 
peduncles; a little later the fruits occupy the ends of the branches, while more and more flowers and buds are 
developed on lateral peduncles and pedicels, till at length the whole becomes one large and intricate, and often quite 
compact, cluster. Short pedicels, gradually swelling into the base of the turbinate calyx ; flowers ordinarily 1 line or 
less in length, mostly 4-parted, later flowers often only 3-parted ; tube of the corolla slender, much longer than the 
calyx, and larger than the short ovate obtuse lacinise; scales ovate or spatulate, shorter than the tube ; capillary styles 
as long as the depressed ovary; capsule globose, 1-1J lines in diameter, bearing the withered corolla on top, often with 
only one or two seeds; seeds 0.6-0.7 line long, oval, oblique, carinate on the inside, with a short linear-oblong usually 
perpendicular hilum. — The western forms collected by Mr. Wright differ from those of the Missouri and Missis¬ 
sippi valleys only by having larger flowers (1.2-1.4 lines long), larger, more depressed, mostly 4-seeded capsules 
(lJ-2 lines in diameter) and larger (0.8 line long) flatter seeds. 
Choisy, in DC. Prod. IX. 458, wrongly gives this very distinct species as a synonym of C. compacta , with which 
it has scarcely anything in common but the hooded capsule; from small flowered forms of C. Gronovii it differs by the 
position of the dead corolla and by the structure of the ovary and capsule. 
\j 47. C. California, Choisy! Cusc. 183; DC. Prod. IX. 457; Hook. & Arn.! Bot. Beechy, 364.— Both 
authors described this plant from Douglas’s specimens under the same name and in the same year (1841); Nuttall, in 
the Hb. Acad. Philad., had named it C. acuminata . —Flowers on slender pedicels, loosely paniculate ; calyx small, 
turbinate with acute triangular, lanceolate or acuminate and sometimes recurved lobes; lacinise very slender, lanceolate- 
linear, acute or acuminate, erect or spreading, in fruit mostly erect or connivent; scales wanting, or indicated by a 
membranaceous inverted arch, with a smooth or crenulate margin connecting the adnate parts of the fila¬ 
ments near the base of the corolla, — in a doubtful variety the scales are fully developed; styles capillary; [499 (49)] 
ovary small, usually globose; capsule enveloped by the corolla; seeds often solitary, subglobose, slightly 
compressed, strongly hooked, 0.5-0.6 line long. 
The different specimens examined vary considerably in the shape and length of the calyx, the proportion of the 
lacinise to the tube, the length of the filaments, the indication of scales, the length of the styles, and even the shape of 
the ovary. 
Yar. a. breviflora : flowers scarcely more than 1 line long, on short pedicels ; lacinise rather longer than tube; 
anthers, filaments, and styles short; seeds several. — Monterey in fields, Hartweg ! 1863. 
Yar. /3. graciliflora : flowers slender, 1^-2^ lines long; calyx often shorter than tube of corolla ; lacinise as long 
as the tube, very narrow ; filaments often short, or as long or longer than the linear-oblong anthers, styles as long or 
much longer than ovary. — California, Douglas ! Fremont! 506 ; Bigelow! 
Yar. y. longiloba : flowers 2-2J lines long ; calyx usually equal to the tube, rarely shorter, sometimes longer; 
lacinise slender, sometimes twice the length of the tube ; subulate filaments as long or longer than the oblong-linear 
anthers ; styles very long and slender. — California, principally, as it appears, on the coast of the southern parts of 
the State, and commonly on some species of Eriogonum: Sta. Barbara, Nuttall! San Diego, Thurber! 570 & 633 ; 
Newberry!
